CAN BEADING AND FLANGING MACHINE.

SPEGIFICATION formingpart of Letters Patent No. 665,478, dated January 8, 1901.

Application filed October 5, 1900.

To all whom it may concern:

Be it known that I, CHARLES W. SLEEPER, a subject of the Queen of Great Britain and Ireland, residing at Lancaster, in the county of Coos and State of New Hampshire, have invented a new and useful Improvement in Can Beading and Flanging Machines, of which the following is a specification.

Beading is the process of forming a raised ridge around the body of the can either on the inside or the outside of the can-body, the object of the bead being to stiffen the body of the can or form a stop for a head or cover, or both.

Flanging is the process of turning a portion of the end of the can-body either inward or outward to form an angle with the surface of the cylinder.

These operations have usually been performed on separate machines, on which the cans have been placed by hand and the pres sure of the rolls applied and regulated by means of a foot-treadle.

The purpose of my invention is the production of a machine adapted to perform both said operations at the same time or either of them separately and in which the said operations, including the regulation of the pressure of the beading and Hanging rolls, are performed automatically.

In the drawings accompanying this specification, Figure 1 is a front view of my invention with portions of the column removed to show details of construction. Fig. 2 is a side View of the same with a portion of the column cut away and showing but one beading device. Fig. 3 is a top View of my machine with two beading devices shown. Figs. 4 and 5 are details of beading device. Figs. 6 and 7 are details of parts for moving and latching the head. Fig. 8 is a detail showing the beading and flanging rolls. Fig. 9 is a detail showing the mechanism for regulating the distance between the beading or flanging rolls. Fig. 10 is a detail giving side View of flanged disk 0 A is the base of the machine, and B the supporting-column, in the upper part of which is journaled a hollow shaft or sleeve e upon one end of which the head a for carrying the beading or flanging devices is loosely mounted in such manner as to be capable of rotation on said shaft.

0 is a flanged disk connected with the head 0 by the barrel 0 The rim of the disk 0 is cut through by four rectangular slots 1 2 34.

c is a segment-gear keyed to the sleeve e and having its face parallel to that of the disk 0 c is a shaft passing through the column B. c is a cam on said shaft.

0 is a cam-rod engaged by the cam c and attached to a latch-bolt c guided between lugs 0 projecting inside the column B.

c is a latch-bolt carried between projecting lugs on the face of the segment-gear e and resting against the coiled spring 0 This bolt projects over the rim of the disk 0 and within its periphery and is adapted to engage the slots in said rim at the proper stages in the operation of the machine.

6 is a shaft driven by a pulley e and carrying a pinion 6 which engages a gear a on the shaft 0. The gear a is provided with a crank-pin e and is connected by a rod e to a pin e upon the sliding rack 6 which is guided in suitable ways in the side of the column B and held in place by a cap 6 The reciprocating motion imparted to the rack e by the revolutions of the gear (2 causes the segment-gear e engaged by the rack, to oscillate through an arc of ninety degrees. When the rack e is at its lowest position, as in Fig. 6, the slot 1 in the rim of the disk 0 is engaged by the latch-bolt c and is in line with the bolt 0 At this .point the bolt 0 rises and entering the slot 1 pushes the latchbolt 0 upward until it leaves the slot, and upon the return mot-ion of the segment-gear the latch-bolt c bears against the inner surface of the rim of the disk 0 as shown by dotted lines, Fig. 7, and on reaching slot 2 is forced into the same by the spring 0 thereby locking the segment-gear c to the disk 0 At the same instant the bolt 0 is withdrawn ous the head 0 is iven an intermittent motion with an advance of ninety degrees and with its period of motion equal to its period of rest.

A shaftf passes through the sleeve c and is provided with bevel-gearsf'f upon each end. The gearf' is engaged by a gear f upon a shaft f which is driven by a pulley f.

The beading or flanging devices, of which there are four, are secured to the face of the head a as in Fig. 1, and described as follows:

Referring to Figs. 4, 5, and 8, c is a journal-box secured to the head 0 and provided with ears (1 c is a swinging frame pivoted upon the pin (i which passes through the ears (Z Screws engage the pins (1 and serve to adjust the position of the frame a, the hole through the frame at this point being oblong to permit of vertical adjustment upon the pin (Z The frame c is bored through in a line parallel with c and carries a spindle d. A similar spindle (Z is carried by the box c The spindles (l d are connected by gears e 0 and a gear 0 upon the spindle d is driven by the gear f upon the shaftf, giving continuous motion to the spindles (l d. The spindles d d are designed to carry beading-rolls d (l or flanging-rolls tl (1 or both. Fig. 8 shows the parts arranged for beading one end of the can and tlanging the other end. The rolls are held upon the spindles by nuts (1 suitable collars al being provided to set the rolls in proper relation to each other. A bracket (Z carries a plate (Z to which is secured a shell (Z for supporting the can-body, of a diameterone-quarter of an inch smaller than the can-body. The bracket (1 is slotted to provide for adjustment of the position of plate d The upper portion of the shell (1 is cut away in a longitudinal slot sufficiently to prevent interference with the action of the rolls. A sliding bar 0 carrying a rack 0 engaging with gear-teeth upon the swinging frame o is guided by a suitable groove in the under side of the journal-box 0 and is provided with a pin and roller 0 to engage the cam-groove c in a sliding bar 0 which is guided in a suitable groove cut into the face of the head 0 The bar 0 is provided with a pin and roller 0 to engage the groove of a cam 0 which is secured to the sleeve 6 and oscillates with it.

It will be understood that as the head 0 revolves the bars 0 are given reciprocating motion by the cam c and impart similar motion to the rack-carrying slide 0, and as the rack engages the gear-teeth upon the swinging frame 0 the spindle d and its beading or fianging rolls are made to approach and recede from the spindle (Z as the head revolves.

In operation the can-body is placed, either by hand or automatically by a forming-machine, upon the shell d of the heading device at the left side of the machine, as shown in Fig. 1, the rolls being held apart at this point by the cam 0 The first motion of the head brings the beading device, carrying the can-body, to its upper vertical position, where the can-body drops by gravity to the plate cl. When the head 0 has remained at this position about one half of its period of rest, the cam e in its oscillation causes the beadi ng-rol Is to grasp the can-body and gradually press it between the rolls while they revolve. The second motion of the head brings the heading device, with its can-body, to a horizontal position at the right side of the machine. During its period of motion the can is revolved between the rolls without any incl-casein pressure; but as soon as the head is at rest the cam again presses the rolls together and increases the pressure gradually during the period of rest. The third motion of the head brings the beading device to its lower vertical position, and during about one half of its period of test the rolls continue their pressure upon the canbody and are then moved apart by the cam 0 and the can-body falls from the machine by gravity. The fourth motion of the head brings it to its lirst position.
